:? I just purchased an E3 with the 12-60 mm Zuiko Digital lens and I cannot get the auto focus to work, it does nothing. It does not respond to the sutter being pushed half way. I followed the manual carefully. Could I have a setting wrong?

Steven R Feb 9, 2008 2:36 PM

I assume that you have checked to make sure that you are not in manual focus mode; and that all the other functions are working (exposure control, etc.)

Take off your lens, then re-attach the lens being careful to not touch the lens release button as you re-attach the lens.

Hi Buddy

Steve's advice is spot on - it looks as if you could well have the camera in manual focus. Also if you haven't updated your camera's firmware to 1.1 I would look into doing that too but make a note of all of your setiings before you do.

Cheers

PS

I think oly should have left the CAF-SF-MF switch and the WB button on the E3. Just my own thoughts.

jorgen Feb 9, 2008 3:35 PM

If Steven's advice fails, consider resetting the camera to the factory settings. Either someone in the shop has played with it or Olympus has taken your camera out for random testing and could have left it in some weird state:

Hi Jorgen

Thanks for that link - my E3 is doing exactly the same thing as described by that original poster with both the 14-54ZD and the 35-100F2. I hadn't really thought about doing a hard reset on the E3 but I will do it tonight and test out tomorrow in ChinaTown.

Cheers

Harj

Thanks Steve and all: It is working now. Not sure what fixed it but I did most of what folks recommended from reading the manual. :G:G

I didn't get a chance to have my say, but here's what I normally post when someone asks this:

This is a problem on EVERY E camera since the original E-1 common with user error if you hold in the lens RELEASE button when attaching a lens, you can turn it PAST the locking point at which point there will be no autofocus or aperture indicated on the camera, it would be shown as "---". The fix to this is to rotate the lens back in the other direction until it locks and communication is engaged.
The main solution is NOT to hold down the lens release button when attaching the lens...it's called RELEASE because it's only to be used to release the lens once it has been locked.

This is a genuine problem with the E3. Mine goes dead as well, and it is nothing to do with holding lens release buttons in etc.

I had been waiting for a Firmware fix, but it came and went with no improvement. I have tried a hard reset, and that does nothing. But given I know it will happen many times when I switch the camera on, and then the AF will continue to work very well, I get around it in my tried and tested method, by twisting the focus ring sharply from one extreme to the other, and the camera/lens comes to life.

OCD, then the contacts are iffy. Send it to olympus before you damage the contacts.

Before sending it in, a suggestion I've heard on some other forums is to gently press in the body contact pins (they're spring loaded) a couple of times; apparently new cameras sometimes have a bit of stiffness in the pins and pressing them in can help get them going. I believe this was suggested by an Olympus tech somewhere, tho can't be sure. It certainly shouldn't hurt the camera if you do it gently.


OCD Feb 12, 2008 3:44 AM

Yes, have tried all those things. I think pressing body pinsis a 'red herring' and doesn't really do anything. It is the process of removing the lens and putting it back on that brings the camera back to life, not the pressing of the pins.The problemcould still be about tolerances, but perhaps more to do with voltages than phyisical contacts. The lens going to sleep only happens on my camera after it has been switchedOFF for a few hours, once working it will carry on all day even if frequently switchedOFF andON again.

Turning the focusing ring is unlikely to damage the contacts, the focusing ring is supposed to be turned.

jorgen Feb 12, 2008 10:31 AM

Up to you, of course. My reaction was due to your use of the word "sharply".

However, as far as I recall, there has been unbelievably few problems with the contacts in all other cameras than the e-3 (apart from the holding-down-the-release button problem Steven and Mike mentioned). If I am right in this, then the e-3 is likely to have a problem with the design of the contacts.

I checked Olympus and here is what they offer for plugins. Last updated July 2006. Unfortunatly I did not see one for the E3.

It may well be a problem with the contacts, but I wouldn't read to much into what you may read on other forums.

When you delve into it the number of actual faulty cameras is very small.The rest are taken up by inexperienced photographers, photographers who don't read the manual, and photographers with unrealistic expectations whomay never have used a DSLR before.The problems with the real faulty cameras are then artificially enlargedbecause everybody explains similar problems but in different ways, so all of a sudden there become more problems and problem cameras than really exist.

Its like the focus problems. Undoubtedly there are probably a few with a back focus problems. But thenmany people get on the bandwagonsaying that they can't focus on venetian blinds so they also have a problem. Yet hardly any cameras are happy focusing on repeating patterns, and just as the E3 manual warns of this so doesthe new Nikon D3, which goes one better and warns of focus problems on skyscrapers! All of a sudden what everybody knows about equipment is thrown out the window and they run around in a panic for nothing.

This so called problem with the pins, solved by pushing them in,is likewise a mistaken conclusioncaused byanalysing to little information (IMO). For some people it works, some it doesn't, some people find their camera goes dead after it has worked flawlessly for long periods, some people find it is dead on startup, some people find taking the lens off and on clears it, some people find taking the battery out clears it. Why would anybody therefore conclude it is the pins that are causing the communication failure? There is no common denominator, but alternatively it is very easy to just blame a few springy contacts that 'plug' the lens into the camera.

OCD, then good luck.

Prior to the E510 that I currently own, I had a Pentax K100D, which at one point was behaving in a similar manner as you guys are describing here. The K100 had a feature that allowed the AF lockto operate via a different button other than the shutter release button (BTW, the E510 has the same functionality - the AEL/AFL lock button can be set so that AF is performed by it rather than the shutter - set SAF Mode 3, CAF Mode 3 or MF Mode 3). In the K100 case,the problemturned out to be with the operation of the shutter release performing the AF. I had to send the camera to Pentax to get fixed.I'm not familiar with the E3 but assuming it has similar functionality as the E510, I'd suggest you set the AEL/AFL lock button to Mode 3 (whatever AF typeyou use - SAF, CAF or MF) to see if the AF works more consistently. Also, the E510 has AF assist when using ZD lenses in M mode. Try that as well if available on the E3.

What about the battery? Have you noticed if the focus problem occur with a freshly charged battery? If the camera focuses OK with afull battery but present problems once the battery is somewhat discharged, it could be that the problem is with the electrical circuit. The camera needs a lot more battery juice than the battery can provide once it starts to discharge. Going back to my old K100, it used 4xAA. I have some Sony 1500 mAh rechargeable batteries that used to work realgood on my H1 but when I tried to use them on the K100, the camera would turn ON and immediately OFF. The problem was resolved by using POWEREX and CR-V3 batteries.So, who knows, maybe there is a design flaw.

A co-worker was experiencing a similar problem with his Nikon D70 the other day. He cleaned up the contacts (camera and lens) with a cotton swab and BINGO. That did the trick. Now, his camera is old so his approachkinda made sense. With the E3 being so new and with so many people reporting focusing issues, I doubt cleaning thecontacts would do the trick.
